Mobile SDK

Introduction

Swedbank Pay Mobile SDK provides an easy way of integrating Swedbank Pay Digital Payments to your Android and iOS applications. The Mobile SDK consists of three components: An Android library, an iOS library, and a backend component with example implementations in Node.js and Java.

The mobile libraries provide standard UI components (a Fragment on Android, a UIViewController on iOS) that you can integrate in your mobile application in the usual fashion. To work, these components need data from the Swedbank Pay APIs, which you must retrieve through your own servers. At the core, the libraries are agnostic as to how the communication between your app and your servers happens, but an example implementation is provided for a server that implements what we call the Merchant Backend API. The Merchant Backend API is designed to transparently reflect the Swedbank Pay API, and the data types used to configure the mobile libraries allow you to organically discover the capabilities of the system.

The SDK is designed to integrate the Swedbank Pay Seamless View Payment UI inside your application’s native UI. It generates any html pages required to show the Swedbank Pay UI internally; it does not support using a Checkout or Payments web page that you host yourself. If doing the latter fits your case better, you can show your web page in a Web View instead. In that case, you may benefit from the collection of information about showing Checkout or Payments in a Web View.

Prerequisites

To start integrating the Swedbank Pay Mobile SDK, you need the following:

  • An agreement that includes Swedbank Pay Digital Payments, specifically Enterprise or Payments Only.
  • Obtained credentials (merchant Access Token) from Swedbank Pay through the Merchant Portal. Please observe that the Swedbank Pay Digital Payments implementations currently available encompasses the paymentmenu scope.
  • Optionally, a HTTPS enabled web server.

It is important to secure all communication between your app and your servers. If you wish to use the example Merchant Backend API to communicate between your app and your server, an example implementation is provided for Node.js and for Java.

Introduction

As the Mobile SDK is built on top of Digital Payments. It is a good idea to familiarize yourself with it first, as the rest of this document will assume some familiarity with Checkout concepts. Note, however, that you need not build a working Digital Payments example with web technologies to use the Mobile SDK.

The Mobile SDK currently provides a mobile component to show Digital Payments Enterprise or Payments Only in a mobile application. The integrating application must set a Configuration, which is responsible for making the necessary calls to your backend. A Configuration for a server implementing the Merchant Backend API is bundled with the SDK, but it is simple to implement a Configuration for your custom server. The Post-Purchase part is the same as when using Checkout on a web page, and is thus intentionally left out of the scope of the SDK.
